US-based electric vehicle manufacturer Tesla has disabled an unapproved autopilot function for Hong Kong drivers upon legal concerns that users will be committing an offence. The function was among driver-assisted features Tesla rolled out worldwide last month that allowed its model S cars to automatically change lanes and speeds, steer within lanes and park with the help of radar, cameras and ultrasonic sensors. While the city’s Transport Department has approved the autoparking capability, it has not endorsed the other two functions.

Earlier, the firm launched its update without government consent, prompting the department to say all “software updates that would affect prevailing driving functions” must be approved. That meant drivers previously using the unapproved functions could be prosecuted.

Carmakers such as Ford and Mercedes-Benz had been helping drivers avoid hazards with their emergency braking and side collision warnings. “Drivers can really get distracted and these features can help them,” Tesla driver Raymond Wu Hung-yip said. “I hope the department can think carefully and approve the features.” Hong Kong has at least 2,000 Tesla cars, but only a limited number of the model S are compatible with the autopilot.
